Response of the Microaerophilic Bifidobacterium Species, B. boum and B. thermophilum , to Oxygen

Response of the microaerophilic Bifidobacterium species, B. boum and B. thermophilum, to oxygen.

We investigated the effects of O2 on Bifidobacterium species using liquid shaking cultures under various O2 concentrations. Although most of the Bifidobacterium species we selected showed O2 sensitivity, two species, B. boum and B. thermophilum, demonstrated microaerophilic profiles. The growth of B. bifidum and B. longum was inhibited under high-O2 conditions accompanied by the accumulation of...

Effect of CO2 on colony development by Bifidobacterium species.

This report investigates the requirement for CO2 for colony formation by Bifidobacterium species in both anoxic and oxic environments. All tested Bifidobacterium species exhibited difficulty in developing colonies in an atmosphere of 100% N2 but developed well when 1% CO2 was present. In the presence of CO2, the oxygen tolerance of the tested species was not improved. In the absence of CO2, onl...

The factors influencing the immune response to hepatitis B vaccine and persistence of the protection.

 Hepatitis B virus (HBV) infection and its sequelae which include cirrhosis and hepatocellular carcinoma is a major public health problem throught the world.The WHO strategy for effective control of HBV infection is vaccination with the surface antigen of virus(HBsAg).The results obtained from a large number of studies demonstrated that the vaccine induces a protective antibody resonse (anti-HB...
